Fast, Reliable Air Duct Cleaning Across North Hills
Air duct cleaning for a typical North Hills home runs $380-$780 for a full system, and most jobs are completed in a single visit. We answer calls live at (844) 685-6342, 24 hours a day, and our Air Duct Cleaning team is usually on the road to North Hills within the hour.
We’ve been driving these streets since 1984. We know the post-war ranches along Nordhoff, the original tract homes near Roscoe Boulevard, and the long driveways that mean our trucks carry every tool we might need so we don’t waste your afternoon running back for parts. North Hills sits in the San Fernando Valley basin where summer heat pushes past 100°F for months and Santa Ana winds blast fine desert dust through every open window. Your HVAC works harder here than almost anywhere in Los Angeles County. That means your ducts work harder too, and when they’re packed with decades of buildup, you’re paying to push air through a clogged system.
Our technicians are background-checked, uniformed, and equipped with Rotobrush and HEPA vacuums on every truck. We show you the camera footage before we start and after we finish. The price we quote on the phone is the price on the invoice.
Why Bellows Air Duct & Vent Co. Is North Hills’s Preferred Air Duct Cleaning Company
North Hills homeowners call us because we’ve earned a reputation for showing up when we say we will and leaving the job done right. Our reviews from this neighborhood mention the same things: we found problems the last company missed, we didn’t try to sell what wasn’t needed, and the 90-Day Done Right Promise meant something when a register started rattling two weeks later.
We’re familiar with the specific housing stock here, the 91343 and 91393 ZIP codes, and the particular problems that come with 50- to 70-year-old duct systems in Valley heat. Response time to North Hills is typically under an hour from dispatch, and our office staff knows the local streets well enough to give you a real arrival window, not a four-hour guess.
Ray Castillo has led this company since its founding, and the K.E.Y.S. values code he established still governs how we treat every home. We’re not a call-center operation sending whoever’s available. Our technicians answer to a live person at our office, and that person can reach Ray directly if something needs attention.
Our Air Duct Cleaning Services in North Hills
Residential Duct Cleaning
Most North Hills homes were built between 1950 and 1975 for aerospace and defense workers, and many still run on original sheet-metal trunk lines with flex-duct branches that have never been properly cleaned. We clean the entire system, not just what’s easy to reach. Our residential service includes supply ducts, return ducts, and the main trunk line, with camera verification at every stage. For the long-time owners who’ve lived in the same ranch on Gresham Street or Hayvenhurst Avenue for thirty-plus years, this is often the first time they’ve seen inside their ducts.
Commercial Duct Cleaning
North Hills has small commercial strips along Sepulveda and Roscoe, plus medical offices, retail spaces, and light industrial facilities that need regular duct maintenance to meet insurance and health requirements. Our commercial crews work after hours to avoid disrupting your business, and we provide written documentation of the cleaning scope for your records. We scale our equipment to the job, from Rotobrush systems for smaller buildings to Nikro truck-mounted units for larger facilities.
Supply Duct Cleaning
The supply side pushes conditioned air into your rooms, and in North Hills homes with quake-damaged or aging flex-duct, this is where we most often find separated joints and collapsed sections. We use camera inspection to locate the problem spots before we start, then agitate and extract buildup with brushes sized to your duct diameter. Clean supply ducts mean even temperatures room to room and less strain on your compressor during those 100°F August afternoons.
Return Duct Cleaning
Return ducts pull air back to your HVAC unit, and in North Hills they’re particularly vulnerable to Santa Ana wind debris and overloaded filters. We emphasize return duct cleaning because this is where the heaviest particulate loads collect, and because dirty returns force your system to work harder for the same airflow. Our HEPA-contained extraction captures what standard shop vacuums recirculate into your home.
Full System Cleaning
This is our most thorough service, and it’s what most North Hills homes need. We clean every accessible component: supply and return ducts, trunk lines, registers, grilles, and the air handler cabinet. Full system cleaning is especially important for homes with original ductwork that hasn’t been serviced since the 1994 earthquake. We complete most full system jobs in one visit, and we show you the before-and-after footage so you can see what was in there.
Video Inspection
Every job starts with a camera. We run a high-resolution scope through your ductwork to document condition, locate damage, and show you exactly what we’re dealing with. For North Hills homeowners who’ve never seen inside their ducts, this is often revealing. The camera doesn’t lie, and it protects both of us: you know we’re not inventing problems, and we know we’re quoting the right scope of work.

Trusted Brands We Service in North Hills
We clean and maintain duct systems connected to all major HVAC brands, and we carry professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies on every truck. These are the same brands serious contractors specify for commercial jobs, and we use them in North Hills homes because they perform. Our parts inventory covers common register sizes, flex-duct diameters, and sealing materials, so most repairs don’t require a second trip. If your system uses Honeywell or Aprilaire air cleaners or UV units, we service those too, and we can recommend compatible upgrades if your current setup isn’t keeping up with Valley conditions.
Common Air Duct Cleaning Problems We See in North Hills Homes
- HVAC contractors flush only the main trunk but ignore flex-duct branches that are 50+ years old with separated joints and debris pockets. We’ve opened systems that were “cleaned” six months ago and found the branches still packed with fiberglass and dust. Our full system approach means we clean what others skip.
- Quake-compromised ducts leak conditioned air into crawlspaces, wasting energy during 100°F summers without the homeowner knowing. The 1994 Northridge earthquake cracked joints and dislodged connections that were never inspected. You feel it as uneven cooling and higher bills, not as a visible problem.
- Santa Ana winds blow fine desert dust into open windows and doors, overwhelming standard filters and loading return ducts with particulates that normal cleaning misses. North Hills residents who open up on mild desert nights wake to fine dust on every surface. That same dust is in your returns, and standard 1-inch filters don’t stop it.
- Original duct wrap in pre-1980 homes may contain asbestos-containing materials dislodged by the 1994 quake. We don’t remove asbestos, but we identify it during camera inspection and refer you to certified abatement specialists. Many long-term owners don’t know what their original duct insulation contains.
The North Hills Earthquake Legacy: What Long-Term Homeowners Need to Know
North Hills sits within the immediate impact zone of the 1994 Northridge earthquake, whose epicenter was less than two miles away. The violent shaking dislodged decades of accumulated dust, fiberglass insulation fragments, and, in pre-1980 homes with original duct wrap, potentially asbestos-containing materials directly into duct systems. Many of those same homes are still owner-occupied by long-term residents who have never had their ducts professionally inspected since the quake.
On a 1958 ranch home near Roscoe Boulevard, we found the original sheet-metal trunk line still intact but the flex-duct branches had separated at three joints from the Northridge quake. Using our Rotobrush and a HEPA vacuum, we removed years of fiberglass insulation fragments and drywall dust that had settled inside, restoring full airflow to the bedroom registers.
North Hills homeowners who repaired drywall and ceilings after the ’94 quake often did not consider that the same shaking cracked duct joints and packed insulation debris inside the ductwork. Technicians working this neighborhood regularly pull out chunks of displaced fiberglass batt and drywall dust from systems that look undamaged from the outside. If your home was built before 1980 and you’ve never had a camera inspection, you don’t know what’s in there.

FAQs - Air Duct Cleaning in North Hills
Yes. The same shaking that cracked your drywall very likely cracked duct joints and packed insulation debris into your flex-duct branches. We’ve found separated joints and fiberglass buildup in dozens of North Hills homes where the interior looked fine. Call (844) 685-6342 and we’ll run a camera through your system so you can see for yourself. Estimates are free.
Weak airflow to specific rooms usually indicates separated flex-duct joints or collapsed branches, common in North Hills homes with original 1950s-1970s ductwork. The main trunk may be clear while the branches are blocked or leaking into the crawlspace. Our camera inspection locates the exact failure point before we quote any work. Call (844) 685-6342 to schedule.
Yes, especially in North Hills where that undersized unit is already working at capacity during summer. Dirty ducts force an overmatched system to work even harder, shortening compressor life and spiking your LADWP bill. Cleaning restores what airflow you have and often reveals duct leaks that are wasting conditioned air. We offer a free second opinion on any written estimate if another company has told you otherwise. Call (844) 685-6342.
Partially. Santa Ana winds blast fine desert particulates through open windows and doors, but if you’re dusting constantly, your return ducts are likely overloaded and your filter is missing the fine particles. Standard 1-inch filters don’t catch what the Santa Anas bring. We clean return ducts and can recommend proper filtration for Valley conditions. Call (844) 685-6342 for an inspection.
Yes, every single job. We run a high-resolution camera through your full system before we start and after we finish. You see what we see. No claims, no guesses. In North Hills, this is particularly valuable because we often find quake damage and pre-1980 insulation that homeowners didn’t know existed. The footage belongs to you. Call (844) 685-6342 to schedule your camera inspection.
